  • How to overlay/downmix two AMR speech files using ffmpeg (with SID mode)

    19 novembre 2019, par Tarrakis

    I have two AMR audio files, extracted from a SIP stream (VoIP call), one file for each person in the conversation.
    The audio files can be played independently using VLC, but it is clear that the SID (Silence Indicator) is being ignored, since one file has a considerably longer playback time than the other.

    I have tried merging them using FFmpeg, as indicated in this post, but I get the following error messages :
    "SID mode is not implemented." "Error while decoding stream #1:0 : Not yet implemented in FFmpeg"

    Does anyone know of an alternative for merging AMR audio files that could support SID mode ?
    Thanks.

  • Watson speech-to-text : Narrowband producing better results than Broadband ?

    22 juin 2017, par Irman A

    I’m using IBM Watson to transcribe a video library that we have. I’m currently doing initial research into it’s efficacy and accuracy.

    The videos in question have OK to very good sound quality and based on Watson documentation I should be using the Broadband model to transcribe them.

    I’ve however tested using both Narrow and Broadband and I’m finding that Narrowband always either slightly better or a lot better in some cases (up to 10%).

    Has anyone else done any similar testing ? It’s contrary to the documentation so I’m a little reluctant to just go ahead and use Narrowband for everything, but I may have to based on the results.

    I’m using ffmpeg to convert the videos to audio files to send to Watson, and the audio files show 48KHz sampling rates, which again means I should be using and getting better results using Broadband.

    Hoping someone out there has done similar research and can help.

    Thanks in advance.
